- To all whom it may concern-.-

Be it known that LWILLIAM JOHN BREWER, a subject of the King of Great Britain, but having applied for naturalizationin the United States, residing at Washington, in the District of Columbia, have invented certain new and useful Improvements in Antifriction Journal- Bearings; and I do hereby declare the following to be a full, clear, and exact description to of the invention, such as will enable Others skilled in the'art to which it appertains to make and use the same. I

Myinvention relates to antifriction journalbearings; and it consists in providing an im- 1 5 proved ball or roller bearing in which the parts liable to wear are detachably mounted and may be readily and rapidly removed and replaced by others without necessitating the removal of the parts to the shop or factory for repairs.

The invention will be understood by reference to the accompanying drawings, in which- Figure 1 represents a section through the 2 5 hub of a Wheel, the axle being shown in elevation. Fig. 2 represents a section along the line 2 2 or 2 2 of Fig. 1 enlarged, the body of the hub being omitted. Fig. 3 is a perspective view showing the cage in which the detachable wear-plates and balls are mounted, and Fig. 4 is a sectional View of a shafthanger fitted with the improved antifrictionrollers. 7

Referring now to Fig. 1, A represents an 3 5 ordinary axle having a cone-shaped bearingsurface A a flange a, and a screw-threaded end a to engage the nut E. B represents a portion of the hub of a wheel. C C represent set wear-sleeves of hardened steel mounted on the tapered portion A of the axle, which sleeves are exteriorly cylindrical. D represents the journal-box, which is secured in the, hub, in any convenient way and is provided with shoulders 01, d, and d abutting against the wear-rings K and the flanged, respectively. E represents a washer held between the nut E and the set wear sleeve C. Mounted over these set wear-sleeves C and C is a ball-cage, which consists of annular heads K and K each provided with a wear-plate K,

detachably connected thereto, as by means of screws is. These heads are provided with hubs K grooved, as at E and are connected together by the tie-plates F. and heads may be secured together in any convenient way, as by meansof a screw passing through the holes f and in (See Fig. 3.) These tie-plates F have longitudinal grooves or channels f in the edges thereof, into which fit the detachable V- shaped wear-plates G. Between these V-shaped wear-plates G balls H are mounted. The parts C, D, G, and II should all be made of hardened material, preferably hard steel.

In the form of device shown in Fig. 4 the hub B of Fig. l is replaced by a shaft-hanger B and the set wear-sleeve C is made cylindrical. The shaft A is provided with set collars F, held in place by screws f to prevent longitudinal motion of the shaft. A represents a pulley or fly-wheel. H are rollers.

It will be seen that all the parts subjected to heavy wear are made of hard metal and so mounted that they may be readily removed and others substitutedwithout requiring the services of a skilled workman and that spare parts may be supplied, which may be put in as required without the expense and delay of sending the bearing to the shop or factory for repairs.

It will be evident that the device may be applied either to coned axles, as shown in Fig. 1, or cylindrical axles, as shown in Fig. 4. It will also be-seen that that part of the bearing which includesthe balls or rollers may be taken out, as one piece and replaced after one or more of the wear-plates G have been removed and replaced or new balls substituted. It will be obvious that rollers may 'be substituted for balls, if desired.

Other advantages of the herein-described construction will readily suggest themselves to any practical mind.

It will be obvious that various changes might be made in the herein-described construction which could be used without departing from the spirit of my invention.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

The tie-plates 1. In a roller-bearing, the combination with the detachable annular heads, and the tieplates connecting the same, of wear-plates mounted in said tie-plates, and rollers mountcd between said wear-plates, substantially as described.

2. In a roller-bearing, the combination with the detachable heads, of the channeled tieplates connecting said heads, detachable V- shaped wear-plates mounted in said channeled tie-plates, and rollers mounted between said wear-plates, substantially as described.

3. In a roller-bearing, the combination with the detachable annular heads adapted to slide over the shaft or axle, and wear-rings detachably connected thereto, of the tie-plates connecting said heads and provided with channels, the detachable wear-plates mounted in said channels, and rollers mounted between said wear-plates, substantially as described.

t. In a roller-bearing, the combination with a wear-sleeve inclosing the shaft or axle, of a cage mounted exterior to said wear-sleeve and comprising detachable heads and tie-plates connecting the same, and wear-plates mounted in said tie-plates, with rollers mounted in said Wear-plates, substantially as described.

5. In a roller-bearing, the combination with a wear-sleeve inelosing the shaft or axle, of a cage mounted exterior to said Wear-sleeve and comprising detachable V-shaped wear-plates mounted in said channeled tie-plates with rollers mounted between said Wear-plates, substantially as described.

6. In a roller-bearing, the combination with a wear-sleeve, of detachable annular heads adapted to slide over the shaft or axle, wearrings detachably connected thereto, tie-plates connecting said heads and provided with channels therein, detachable wear plates mounted in said channels, and rollers mounted between said wear-plates, substantially as described.

7. In aroller-bearing, the combination with the detachable annular heads with wear-rings detachably secured thereto and tie-plates connecting said heads, of Wear-plates mounted in said tie-plates, and rollers mounted in said wear-plates, substantially as described.

8. In aroller-bearin g, the combination with the detachable annular heads, and wear-rin gs detachably secured thereto, of the channeled tie-plates connecting said heads, detachable V-shaped wear-plates mounted in said channeled tie-plates, and rollers mounted between said wear-plates, substantially as described.

9. In a roller-bearing, the combination with detachable annular heads adapted to slide over the shaft or axle, with wear-rings detachably secured to said heads, of the tieplates connecting said heads and provided with V-shaped channels therein, the detachable V-shaped Wear-plates mounted in said channels, and rollers mounted between said wear-plates, substantially as described.

In testimony whereof I alfix my signature in presence of two witnesses.

WILLIAM JOHN BREWER.
